Title: Surface acoustic wave device and surface acoustic wave resonator
Inventor: MATSUMURA SADAO
IPC: H01L41/18
Filed: 1995-11-27
Abstract: PURPOSE: To realize reproducibility with excellent initial characteristics by using selectively a lithium tantalate(LT) single crystal substrate whose crystal Curie temperature is within a specific temperature so as to form an electrode pattern onto the substrate. CONSTITUTION: In the surface acoustic wave(SAW) device using an LT single crystal substrate, the LT single crystal substrate whose crystal Curie temperature is in the range between 604 and 609 deg.C is used selectively to form an electrode pattern on the substrate. That is, the SAW device is manufactured by selectively using the LT single crystal substrate whose crystal Curie temperature is in a range between 604 and 609 deg.C based on the relation of the crystal Curie temperature (Tc) and a speed of a surface acoustic wave (Vs) and the relation between a resonance frequency of the SAW resonator and the speed of the SAW. Then the initial characteristic is obtained with excellent reproducibility and the fluctuation width of the crystal Curie temperature of the LT single crystal substrate is restricted and the yield of the SAW devices is considerably improved.

Abstract: PURPOSE:To improve pattern recognition, associative memory, and parallel arithmetic process by making the light intensity of each image formed by a two-dimensional lens alley constant regardless of lens position by using a device for modulating the intensity of light, besides a spatial light modulating device. CONSTITUTION:A neural network is composed of a light source 20 for irradiating a manuscript 22, a two-dimensional lens alley 30 for forming input images as many as the number of neurons, a spatial light modulating device 60 for making the intensity of image formed constant, a spatial light modulating device 40 that corresponds to the synapse connection of neural cell, and of a light threshold device 50 for taking the sum of inputs for threshold process. The device 50 is composed of, for example, a photo-control layer and of a luminous layer, and if the sum of the intensity of the light input to the device 50 is not less than a fixed value, the device is turned ON, and light is emitted, while if it is not more than the fixed value, emission does not occur. The intensity of the image input to the device 50 is not dependent upon the location, and thus will be constant, while the convergence of learning is good and the recognition rate at the time of association will also be good.

Title: Pulse mixing device
Inventor: YAMAMOTO YOSHIYUKI
IPC: H04N5/53
Filed: 1988-12-06
Abstract: PURPOSE:To switch only a pulse amplitude without changing a level of pulse tip by selecting a DC level being a 2nd prescribed level from part of a level of a mixed pulse or an offset voltage from a level of a synchronizing signal tip at an output of a clamp circuit. CONSTITUTION:If there is any difference in two input levels to a comparator 7, the error voltage is amplified and outputted to control a gain control ampli fier (GCA) 2 via a level detector 10 to make the difference zero, then the level is Vp1+Vs1=VR-VO when a 3rd input terminal 80 is at a low level, Vp2+Vs2+ Vo2=VR-Vo when the terminal 80 is at a high level. Thus, the relation of Vs1-Vs2=Vp1-(Vp2+Vo2) exists and also the relation of Vp1=Rs2(I1+I2)=Vp2+ Vo2 exists, even when the level of the 3rd input terminal 80 is low or high, that is, the level of the mixed pulse is switched, the synchronous signal level is constant. Thus, even if the level of the mixed pulses is switched, the potential of the pulse tip is unchanged.

Title: Lead frame for semiconductor integrated circuit device and semiconductor integrated circuit device
Inventor: WAKABAYASHI YOSHIMASA
IPC: H01L23/12
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To reduce an area of a sealing package by forming an island part, where the whole part is worked in a spiral shape or a meandering shape. SOLUTION: In a lead frame 2, e.g. a mount-island part itself of a semiconductor element is worked into a spiral shape. In the periphery of the spiral-shaped mount-island part 1, a plurality of inner lead parts 3 are arranged which are to be arranged in a package, after a semiconductor integrated circuit device has been completed. When the semiconductor integrated circuit is manufactured by using the lead frame 2, the spiral-shaped mount-island part 1 functions as an inductor by cutting individually the lead frame 2 from a lead frame retaining part. That is, both the mounting function and inductor function can be realized by using only the mount-island part. As result, the miniaturization of the lead frame and the miniaturization of a sealing package as well can be achieved.

Title: Master disk for production of optical disk
Inventor: SUZUKI FUMIYUKI
IPC: G11B7/26
Filed: 1987-12-09
Abstract: PURPOSE:To form holes or grooves of a precise size at desired precise depth to desired places by providing an intermediate layer which is soluble in an acid soln. and does not interfere with resist layers between the resist layers which are different in sensitivity and are formed on a substrate. CONSTITUTION:The low-sensitivity photoresist layer 2 consisting of a quinone diazide photosensitive material and novolak resin is formed at 2,700A thickness on the glass substrate 1 and the intermediate Ni layer 3 is formed at 50A thickness in contact with the resist layer 2. The high-sensitivity photoresist layer which consists of the quinone diazide photosensitive material and novolak resin and has the sensitivity higher than the sensitivity of the resist layer 2 is formed at 700A thickness in contact with the intermediate Ni layer 3. The Ni intermediate layer 3 is soluble in the acid soln. but is not attacked by the solvent contained by the resist layer 2 and the resist layer 4. The intermediate layer 3 is, therefore, capable of separating the resist layer 2 and the resist layer 4 without mixing these layers. The formation of the holes or grooves having the precise depth size is thus possible.

Title: Wireless transmitter-receiver
Inventor: NAGAMOTO SHUNICHI
IPC: H04Q9/00
Filed: 1988-12-07
Abstract: PURPOSE:To conform to the weak radio wave rules and to improve the reception sensitivity by providing separately a reception antenna connecting to a reception means and a transmission antenna connecting to a transmission means and making the length of the reception antenna variable. CONSTITUTION:The transmission antenna 4 is provided separately from the reception antenna 2 as the fixed structure and sends a radio wave signal with a transmission power satisfying the leak radio wave rules. Moreover, the reception antenna 2 is configurated to be telescopic by using a rod antenna or the like and the length of the antenna is as required made variable. If the reception sensitivity is deficient in the actual installing state, the length of the reception antenna 2 is prolonged to receive a radio signal from the other equipment in an excellent way. Furthermore, as to the transmission, since the transmission antenna 4 is provided as the fixed structure entirely separately from the reception antenna 2, the transmission power is always kept to a level satisfying the weak radio wave rules.

IPC: G02B6/12
Filed: 1987-12-09
Abstract: PURPOSE:To suppress the crosstalk by inter-channel interference between wavelengths by providing a resistance layer on or in a substrate and laminating a low-refractive index layer, core waveguide and clad layer successively thereon, then impressing voltage across this resistance layer. CONSTITUTION:The resistance layer 200 is formed only in the region of the substrate 100 shown by the broken line in the figure. A high-concn. layer is formed in parts 11, 12 where electrodes of heating elements are to be formed. A film 300 is deposited atop the substrate 100 and light guides 400, 401 are formed thereto. The entire part is enclosed by a clad layer 500. Through-holes are formed to the required parts where the surface is to be exposed in order to draw the electrodes out of the heating elements, then the electrodes 13, 14 are formed. The control of the central wavelength of the spectral characteristics by changing the temp. is, therefore, possible by passing the current to the resistance layer 200. The crosstalk by the inter-channel interference between the wavelengths of the light signals is thereby suppressed.
